Bacteria, Virus

Bacteria: 1) tiny one-celled organisms present throughout the environment that require a microscope to be seen. While not all bacteria are harmful, some cause disease.; 2) germs or “bugs” that can infect people, animals, plants, other living things, soil, water, and other parts of the environment; germs that grow and can cause sickness; we can treat these sicknesses with medicines called antibiotics. Virus: germs that need a host, which is a living thing, such as people, animals, or plants, to survive. The germs get into a cell, take it over, and force it to copy the germs so they increase in number and spread through the body.
